How We Ranked These CPAs
Our Guide Score percentage combines verified ratings, review volume, web presence, profile completeness, professional credentials, press recognition, and experience. Scores are normalized across categories where positive evidence was captured, so a missing category is shown as not captured rather than counted as a failing grade. No business can pay for a higher ranking.
Data sources include Google Business Profile, professional registries, portfolio sites, press databases, and direct business submissions. Every piece of data is publicly verifiable.
